The quality of the welding of the coffee capsule directly affects the airtightness of the entire coffee capsule and ultimately the safety in the process of making the coffee. In order to realize the non-contact real-time automatic detection of the welding quality of coffee capsule aluminum foil

a machine vision-based coffee capsule aluminum foil welding quality inspection system is designed

including vision system and online detection software.The aluminum foil welding quality inspection system first obtains the welding image of the aluminum foil on the bottom of the cup by hardware such as a camera lens

and then performs filtering

threshold segmentation and edge extraction on the collected image through software

and measures four key parameters of the concentricity of the aluminum foil and the cup

the width of the welding ring

size of the aluminum foil

and bonding ratio to classify and identify the welding defective products and good products during the production process

which provides realtime quality inspection for the production of coffee capsules.
